PRIVATE AI CATALOGUE

One private team catalogue for skills, prompts, MCPs, secrets and agents.

Joyst gives your team one private catalogue for its skills, prompts, MCPs, secrets and agents. It controls who can use what, without sitting between your agents and the tools they rely on.

THE PROBLEM

AI is spreading. Control hasn't kept up.

Skills are scattered
Skills and prompts live in chats, documents and personal laptops. Without a single source, teams can't track versions or withdraw what is out of date.
Tools go untracked
MCP servers and secrets multiply quickly. Nobody has a clear view of what exists or who can see it.
Drafts go live
Unfinished work gets shared as if it were approved. Joyst keeps work in draft until someone publishes it.

Everything your team's AI needs. In one place.

Joyst keeps skills, prompts, agents, MCP servers and secrets in one private catalogue. It does not sit between your agents and the tools they call.

One catalogue

Skills, prompts, agents, MCP servers and secrets sit side by side.

Control

Organise people into groups, set permissions and publish only what is ready. Connecting, publishing or changing an item writes an audit entry.

Skills

Skills that travel

Versioned skills that your agents can reuse across platforms.

MCPs

Tools, explained

Record each connected server, with notes written by your team.

Secrets

Private by default

Secrets are encrypted and stay private unless you choose to share them.

Questions before you sign up

Joyst catalogues skills, prompts, agents, MCP servers and secrets. The catalogue is private to your organisation. It is not a public marketplace.

When skills, prompts, MCP servers and keys live in chats, documents and personal machines, nobody owns the approved copy. A private catalogue gives your team one place to version them, control access and reuse them across the AI tools you already pay for.

Developer portals such as Backstage, Port, OpsLevel and Cortex catalogue software services. Joyst catalogues the skills, prompts, MCP servers, secrets and agents your teams use with AI. Keep your IDP and use Joyst beside it.

Joyst is for organisations where AI use is spread across many people and tools. That includes platform engineering, AI operations, agencies and security-minded teams that need a shared catalogue with real access control. It is not designed as a personal prompt list.

Choose Joyst when more than one person works on the same prompt or skill. Joyst keeps an admin log of changes. Each item also has its own version history. Notion and Slack are fine for notes and chat. They do not replace that log, or the version history on each item.
